Heckler & Koch P9S model.

Not to be confused with the Heckler & Koch P7.

The Heckler and Koch P9 is a 9mm semi-automatic pistol.

DescriptionEdit

The polymer-framed P9 was the first to use a variation of H&K's roller delayed blowback system in a pistol format and polygonal rifling now common in H&K designs. Design began around 1965 and production ran between 1969 and 1978. Only 485 single-action P9's were produced and were discontinued in 1970. A traditional double-action version, the P9S was manufactured in greater quantity. It was also adopted by the US Navy for use with a sound suppressor.

The P9S trigger operates as a traditional double action. There is a lever on the left side of the pistol grip to both decock a cocked hammer or to manually re-cock it for a single action first shot, a feature first observed on the Sauer 38H. A further function of the decocking lever is to release the slide stop. The hammer is concealed within the slide (also similar to the Sauer) with a protruding pin at the rear of the slide as a cocking indicator. The operating spring surrounds the barrel, allowing for a lower bore axis than pistols such as John Browning's M1911 that have the operating spring below the barrel. A manual safety is located at the left/rear of the slide and the magazine-release is heel-mounted.

A compact version with a shorter barrel and slide, the P9K, was made in prototype form, but was never put into production. In addition to the standard P9S, a P9S Target model was also offered. This model included a taller front sight, a windage and elevation adjustable rear sight, an adjustable trigger over-travel stop, and an adjustable trigger that could be adjusted down to as low as approximately a 2.5# pull. The P9S Target model was offered in both 9mm as well as .45 ACP. The P9 is also offered in 7.65×21mm Parabellum.
